Description

Direct insertion device for operation panel of frequency converter

Technical Field

The utility model relates to a converter operating panel's installation and dismantlement structure realize quick reliable installation and dismantlement, in particular to converter operating panel cut straightly device.

Background

The operation panel or hand-operated panel of the frequency converter is used for displaying the setting conditions of various parameters, and is also a component for the frequency converter to receive commands, so the operation panel or hand-operated panel is also commonly regarded as a human-computer interface of the frequency converter. The frequency converter operation panel is generally installed on a cover or a panel of a cabinet, and the operation panel is manually taken down from the frequency converter cover or the cabinet and can be connected with the frequency converter body through an extension cable for communication.

The common mounting structure of the operation panel of the frequency converter in the prior art is rotary mounting, the assembly deviation of the connector is large, the assembly of the connector is difficult, and even the connector is damaged due to interference and collision during assembly; meanwhile, pits for taking out the operation panel are arranged at the top or two sides of the operation panel, so that the mode is labor-consuming when the operation panel of the frequency converter is disassembled, and the overall appearance of a product is influenced.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a converter operating panel cut straightly device, its operating panel and main control board data interface installation and the convenient reliable mode of dismantling.

In order to solve the technical problem, the utility model discloses an operating panel who packs into the apron pit, a reset spring and bracket with the button linkage, operating panel's connector socket with be fixed in the inside main control board connector plug of converter and insert perpendicularly and be connected. When the operation panel is disassembled, only the button needs to be pressed, the reset spring is stressed and twisted, the bracket rotates around the bracket fixing pin as a lever, the bracket raised heads positioned on two sides of the front end of the bracket evenly support the operation panel from two sides of the stress center of the operation panel, the operation panel is manually taken down, and after the external force applied to the button is removed, the button and the bracket are restored to the initial position under the action of the reset spring. The button is connected in the long circular groove at the tail part of the bracket through a button fixing pin and can slide in the long circular groove.

In the technical scheme, the raised heads of the bracket on the two sides of the front end of the bracket are in the initial positions, namely are sunk in the grooves at the bottoms of the concave pits of the cover plate, so that the assembly of the operation panel is not influenced. After the operating panel is removed and the button is loosened, the bracket is restored to the initial position under the action of the return spring, when the button is pressed to the lowest point limit position, the cantilevers at two sides of the bracket just touch the left end of the groove formed at the bottom of the concave pit of the cover plate, and the related structural parts are prevented from being damaged by excessively pressing the button. The bracket raised heads on the two sides of the front end of the bracket are equidistantly distributed on the two sides of the stress center of the operation panel, so that the operation panel is supported in a balanced manner, and the bracket is provided with a notch for limiting the reset spring to prevent the reset spring from axially moving on the bracket fixing pin.

The utility model discloses an apron is a whole working of plastics rather than the two fulcrums at the back, and through bracket fixed pin connection bracket as the lever fulcrum, the apron is located to open spherical pit in the button and is used for making things convenient for button operation.

The utility model discloses the structure is mutually supported by converter operating panel, apron, reset spring, button, bracket, utilizes lever principle to realize converter operating panel installation and perpendicular up-and-down action when dismantling, guarantees that converter operating panel connector socket is connected and is separated with main control board connector plug in the vertical direction, further improves the connection reliability, operating panel need not the rotation angle and packs into, the connector is not fragile, need not to set up the pit of taking out operating panel on the apron, can not influence the whole outward appearance of product.
